1. Boaz Weinstein

Age: 36

At Deutsche Bank, Weinstein earned billions using a type of trade called "capital structure arbitrage," in which he would exploit differences in the price of a company's various
bonds and stock.

The chess "life" master was a star trader for most of his 11 years at the bank. But after his fund suffered a $1 billion loss in 2008, about 18% of the money he managed, he left
Deutsche and is now running his own hedge fund, called Saba Capital Management.

Weinstein has reportedly raised more than $250 million for his new fund. "If he made a mistake he'll learn a ton from it," William Ackman, the CEO of hedge fund Pershing Square
Capital, told The Wall Street Journal earlier this year.
